“…This result is attributable to differences in the particle types in the sediment: sandy sediment at the Hirakata Bridge (moisture content of 9% with 79% sand, 3% silt, and 0% clay) and silty sediment at the Suita Bridge (moisture content of 49%, but no available data for its composition). Similar observation has also been reported in previous studies dealt with different pharmaceuticals [60,67]. respectively, with no clear difference between both of the sites.…”

“…After incubation, each solution was recovered by filtration through a GD/X glass fiber filter and the concentrations of the anticancer drugs were measured by LC-MS/MS. In the cases for the experimental sorption, the logK d values for the river sediment were determined from the slope of the linear regression lines produced by the initial and equilibrated concentrations in the dissolved phase and the dry weight of the adsorbent [24,60,61].…”

This article reviews the pollution status of anticancer drugs present in the Yodo River basin located in the Kansai district of Japan, covering both the soluble and insoluble (adsorbed on the river sediments and suspended solids) levels. Procedures ranging from sampling in the field and instrumental analytical methods to the data processing for mass balance estimation of the target basin are also described. All anticancer drugs concerned with this article were detected in sewage and river waters, where the presence of bicalutamide (BLT) was identified at considerably high concentrations (maximum 254 ng/L in the main stream, 151 ng/L in tributaries, and 1032 ng/L in sewage treatment plant (STP) effluents). In addition, sorption distribution coefficient (logKd) values showed a tendency to become higher in the silty sediments at Suita Bridge than in the sandy sediments at Hirakata Bridge; these trends were supported by the results of the laboratory-scale sorption experiment. STPs were concluded to be the main sources of the anticancer drug load in the river, and a mass flux evaluation revealed that the effect of attenuation in the river environment was small. The effectiveness of ozonation in the sewage treatment process for removal of these anticancer drugs was further confirmed. The present article should be of value for facilitating the environmental risk assessment of a wide range of drugs in a broader geographical area.

“…Although the types of steroids detected in the suspended particles were similar to those detected in the sediment, the total concentrations of detected steroids were almost 1-2 orders of magnitude higher than those in the sediment (Table 1). As compared to sediment, suspended particles have a greater tendency to enhance steroids' bioavailability in fish through ingestion or respiration across gills with smaller particles and better mobility (Sangster et al, 2015).…”

“…The transport mechanism of hormone in runoff is governed by the partitioning between sediment-associated and aqueousfraction and is the underlying reason for the presence of hormones in surface runoff from agricultural fields. Sangster et al [47] studied the sorption of 17␤-estradiol, estrone, progesterone, and testosterone in silty loam sediments and concluded that at low aqueous concentrations (1 ng/L) up to 93% of sediment associated hormone found in the fine fraction and the smaller particles have a greater tendency to be suspended in and move with the water column. The low frequency of detection in our study might be correlated with the phenomenon as the reported concentrations are based on analyzing the aqueous portion of samples.…”

h i g h l i g h t s• Hormones and metabolites were detected in runoff from test plots fertilized with cattle manure.• Composting can reduce the hormone concentration in manure compared to stockpiling.• About 10% of applied hormones can be lost through the dissolved phase of runoff. a r t i c l e i n f o a b s t r a c tRunoff generated from livestock manure amended row crop fields is one of the major pathways of hormone transport to the aquatic environment. The study determined the effects of manure handling, tillage methods, and rainfall timing on the occurrence and transport of steroid hormones in runoff from the row crop field. Stockpiled and composted manure from hormone treated and untreated animals were applied to test plots and subjected to two rainfall simulation events 30 days apart. During the two rainfall simulation events, detection of any steroid hormone or metabolites was identified in 8-86% of runoff samples from any tillage and manure treatment. The most commonly detected hormones were 17␤-estradiol, estrone, estriol, testosterone, and ␣-zearalenol at concentrations ranging up to 100-200 ng L −1 . Considering the maximum detected concentrations in runoff, no more than 10% of the applied hormone can be transported through the dissolved phase of runoff. Results from the study indicate that hormones can persist in soils receiving livestock manure over an extended period of time and the dissolved phase of hormone in runoff is not the preferred pathway of transport from the manure applied fields irrespective of tillage treatments and timing of rainfall.
